Default FZ100 draining batteries when turned off

Hi guys,

I've been having this problem with my FZ100 for a couple of weeks already, and I'm sending the camera to panasonic now to see if they can do anything about it, but I was wondering if anybody else here ever heard of the problem:

The camera works correctly overall, takes pictures, etc. The roblem happens when you turn it off and leave it for a few hours (sometimes 1, sometimes at least 3-4, it seems): the camera fails to turn back on when you change the switch, and only taking the batteries off solves the problem.

During that time, the battery also seems to be drained. So for example, if you leave a charged battery in the camera overnight, by next morning the battery will very likely be empty. I have two new Panasonic batteries, and it happens with both.

Any ideas?

Either the battery charger is faulty, not sensing the charging of the battery, unlikely if you have three batteries, or the camera has developed a fault.

With complex cameras like this, it is very hard to say what is causing the problem unless you can change pcb's and check the amount of current drawn by the various pcb's.

You have chosen the only option available to you.

Good luck and I hope you don't have too long a wait to get it returned repaired.

Thanks.. that's my feeling as well.

Anybody has any idea on how long it takes for panasonic to do this kind of analysis/fix?

This is my first Panasonic camera, and have no idea of times involved.

A few years ago, my Olympus was sent away, and was back within two weeks.....

I hope it is quick but judging by what you have said, I presume, there's something shortened inside. My cell phone keeps doing that

Hope that it all works out for ya. When I shipped my FZ100 back cause of a faulty LCD screen, it took 2 days for the camera to get shipped to them, and they replaced it with a different one which also took 2 days of shipping. So, it I was without a camera for about a week. As soon as my camera got there, they sent me a different camera. Not sure if they will do the same for you, but hope that it all works out for ya.

It sounds like you have a short somewhere in the camera. I have left my battery in my camera for a couple of weeks, and have no issue with dead batteries.

Thanks Da Wolf, I hope they also do that.. I used to leave batteries in all the time as well, and they would stay charged..

They should be receiving the camera today, hopefully they'll do that under warranty for me, which expired yesterday, after I created the request online..

It's good to hear that your warranty expired after you created the return request

Les hope they replace the camera for you.

I'm a field engineer for laboratory instrumentation and degreed in electronic for 30 years.

I'd bet that the hold up capacitor, for memory, is 'shorted' or failed. It's purpose is to store up
enough of a charge so that memory setttings are not forgotten while changing a battery.
Normally they're in 0.1 up to 1.0 Farad at 3.3
volts (about) and hold much less power than
would a Lithium coin cell.. but they're rechargable (unlike coin cells) and last longer than
a NiMH battery normally would (indefinitely is the hope but they occasionally fail)

They're called
Supercaps, Ultracaps, Electric Double Layer Capacitors



sit digikey.com p11069ct-nd
Here's an example of one for a Olympus C750 camera

They show you how to replace, in the Olympus, here:
